FURNACE FOR .BURNING DIRT.

the furnace, there being provided beneath said opening and through the rear wall 4 adjacent to its bottom a draft-opening 13, while at the front of the furnace there arises vertically upward from the top 6 a stack or iiue 14:.

Arranged upon the outer faces of the side To all whom, it' mag/concern:

Be it known that I, ALBERT P. WARREN, a citizen of the United States, residing at Adairville, in thevcou'nty of Logan and State lof Kentucky, have invented a new and useful Furnace for Burning Dirt, of which the following is a specification.

My invention relates to furnaces, being especially directed to a furnace for burning and preparing soil for use in seeding plants, and has for its objects to produce a simple inexpensive device of this character which will be eiicient in operation and one inlwhich the soil after being prepared may be readily discharged without passing directly through the furnace-fire. Y

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of my improved furnace. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a vertical transverse section. l

lReferring to the drawings, 1 designates the furnace, preferably of the form herein shown, and comprising side walls 2,a front outwardlycurved end wall 3, a rear wall 4, an open bottom 5, and an open-work or sieve-like top 6, which is preferably composed of perforated sheet metal, of which the perforations 7 are spaced uniformly one from another, being herein shown as arranged in transverse rows. The sides and rear end of the furnace are profaces with a substantially continuous inwardly-projecting horizontal flange 8,formed from angle metal bolted or otherwise secured in place at a plane somewhat below the upper edges of the wall and constituting a support upon-which the perforated top 6 rests, whereby said walls extend above the top and form a vertically upstanding'flange 9, surrounding the sides and rearV end of the top, this flange being completed at the front by a supplemental portion or extension 10, riveted or otherwise secured in place.

11 is a door hinged at the rear end of the furnace and normally closing an opening 12, through which fuel is delivered for charging from end to end 'are horizontal stay-bars 15,

opening 12 and carrying at their ends rings or other suitable handpieces' 16, by which the furnace may be transported. These staypieces are maintained in placeby tie bolts or rods 17, extending furnace Vand further sustaining supportingbars 18, arranged upon the inner faces of the side walls of the furnace symmetrical with the stay-bars 15, the bars 18 being provided upon their upper edgesl with spaced notches orseats 19, which receive the ends of transversely-disposed grate-bars 20.

Disposed within the furnace above the grate, and preferably directly beneath the top 6, is a shield or cut-off 21, composed of perforated sheet metal, bent to display in cross-section the form of an inverted V, said. shield being sustained for a rocking motion by a pivotal rod 22, extending longitudinally through the furnace at the transverse center of the latter and having bearings in the end walls 3 and l1. This rod is provided at its forward end with va ring or other suitable handle 23, by which the rod may be manipulated for rocking the shield.

24: indicates a tray or receptacle, preferably rectangular inform, as herein shown. This tray is seated upon the top 6 within the flange 9 and has its bottom 25 provided with perforations 26 coincident in size and arrangement with the perforations 7. The tray is of a length somewhat less than the distance between the end walls of the flange, this difference in lengtlibeing equal to the diameter of one of the perforations 7 or 26,v whereby the tray will have a movement sufficient to bring said perforations into or out of register, thus providing for regulating the size of or wholly closing the ,openings 7.

In practice fuel is placed upon the gratewalls 2 and extending longitudinally thereof i disposed in a plane with the lower edge of transversely through the while at the same time any seeds of weeds,

grass, or the like which the soil may contain or, in fact, other matter which will be injurious to the young plants is wholly destroyed, and the soil is perfectly prepared for use in seeding young plants. After the soil has been sufficiently treated it is sifted through the perforations 7 26 and passes downward through the furnace for discharge through the open bottom of the latter. During its passage through the furnace the material is defected and directed by the shield 21 outward toward the sides of the furnace, and should the soil during its passage between said parts become packed or choked between the furnace-walls and shield the latter may be oscillated on its pivot to loosen and insure proper downward feeding of the soil.

From the foregoing it will be seen that I produce a device of simple construction'which is admirably adapted for the attainment of the ends in View and one which is particularly eicacious for treating the soil during rainy seasons when the ground is so wet as to render burning of the soil under ordinary methods impracticable. In attaining these ends it is to be understood that I do not limit myself to the precise details herein set forth, inasmuch as minor changes may be made therein without departing from the spirit of the invention.

Having thus described my invention, what I claim isl. In a furnace of the type described, the combination with a grate, of a receptacle disposed above the same and having a perforated bottom, and a deflector pivotally sustained between the receptacle and grate.

y sustained between the 2. In a furnace of the type described, the combination with a grate, of a receptacle disposed above the same land having a perforated bottom, and a perforated defiector pivotally receptacle and grate, the walls of said deflector in cross-section being arranged to diverge downwardly.

3. In a furnace'of the type described having a perforated top, the combination with a grate, of a receptacle disposed above the perforated top and having a perforated bottom, one of said parts being movable for bringing the perforations into and out of register, and a deflector situated between the receptacle and grate.

4. In a furnace of the type described having a perforated top, the'combination with a grate,

of a receptacle disposed above the perforated top and having a perforated bottom, said vreceptacle being movable for bringing the perfor-ations into and out of register, and a de- Hector situated between the receptacle and grate.

5. In a furnace of the type described having a perforated top and an upstanding flange surrounding the latter, the combination with a grate, of a deflector situated between the perforated top and grate, and a perforated member cooperating with the top to regulate the size of its perforations.

6. In a furnace of the type described having a perforated top and an upstanding fiange surrounding the latter, the combination with a grate, of a defiector situated between the perforated top and grate, and a movable perforated member coperating with the top to regulate the size of its perforations.

In testimony that I claim the foregoing as my own I have hereto alixed my signature in the presence of two, witnesses.

ALBERT P. WARREN.
